  • Performance analysis of electric vehicle high voltage wiring harness terminal crimping
    Dec 22, 2022 Performance analysis of electric vehicle high voltage wiring harness terminal crimping
    With the rapid development of new energy automobile industry, new energy wiring harnesses get development opportunities. The difference between a high-voltage wire harness and a low-voltage wire harness is that the high-voltage terminal tends to generate heat due to the high current passing through the terminal. As a result, the mechanical strength of the terminal and the insulation performance of the wire harness are decreased, and the oxidation of the conductor further aggravates the heating.   High voltage terminal crimping needs to consider both the reliability of the crimp and the low temperature rise of the crimp. High voltage terminals are commonly crimped Crimping, resistance welding, high frequency welding Crimping uses crimping equipment and dies to join wires and terminals together through a crimping process. High frequency welding is the use of high frequency welding machine to weld wire and terminal together. Resistance welding is the use of special resistance welding equipment to connect the wire and terminal together. Advantage Simple operation, convenient maintenance, low manufacturing cost, high operating efficiency, suitable for mass production. Shortcomings The wiring harnesses and terminals that require high current pass rate and low resistance after the connectors are connected cannot be met. Figure 1 shows the common crimping modes of large square high voltage terminals, which are hexagonal closed terminals. The advantages of ordinary crimping are obvious, but how to make ordinary crimping develop advantages and avoid disadvantages, as far as possible to reduce the resistance is particularly important. Reducing resistance means reducing heat, reducing product temperature rise, making product life and quality better.   Hazard of terminal heating After the terminal is heated, it is easy to oxidize itself and the contact surface of the conductor of the wire, generating oxide film, so that the contact resistance increases, and the increasing speed increases exponentially with the increase of temperature, further increasing the terminal temperature rise speed, and serious fire will be caused. At the same time, the elastic element of the contact structure will be annealed, the contact pressure will be reduced, and the contact resistance will be increased further. In addition, the heating will make the wire insulation layer connected to the terminal aging brittle, resulting in a decline in insulation performance, there is the risk of leakage overheating caused by fire.   As shown in Figure 2, the high voltage wiring harness has three heat sources. Terminal three heat source : Conductor Conductor: The conductor itself has a resistance. The smaller the cross-sectional area, the higher the resistance. Resistance will cause heating. Terminal compaction: insufficient compression ratio will make the conductor loose, resulting in large resistance, easy to heat. Excessive crimping is easy to cause small cross-sectional area,...

  • How to draw auto wire harness drawing?
    Dec 20, 2022 How to draw auto wire harness drawing?
    Solution 1:   According to the wiring harness configuration list of the vehicle and the wiring harness direction in the 3D wiring diagram, the measurement tools in CATIA are used to measure the required sizes of each trunk, branch, buckle, cable tie and rubber parts according to the drawing requirements of the wiring harness diagram. The 2D diagram can be arranged through reasonable design, and the outline of the wiring harness diagram can be basically determined.     Solution 2: In the process of automobile circuit design, in order to understand the actual situation of automobile electrical equipment in detail and facilitate the arrangement and connection of automobile circuit, engineers need to rely on the schematic diagram, automobile circuit diagram and application diagram. Although the diagram reflects the actual installation position of the electrical equipment on the vehicle, the criss-cross wires in the diagram increase the difficulty of reading the diagram. In order to make the circuit diagram more close to the reality, it is often necessary to draw the wiring harness installation diagram. Wiring harness diagram is the whole car circuit diagram drawn according to the actual installation position of electrical equipment on the car, mainly based on the formation of wiring harness, the drawing surface of the line is less, the expression of the connection between the components has become its main content, in order to express the color of the wire, the terminal code of the joint, often supplemented with wiring harness grouping and terminal number table and wiring harness terminal wiring table. The contents of the wiring harness First, the composition of the wire harness The automobile wiring harness diagram is composed of multiple wiring harnesses, including main line harnesses and branch wiring harnesses. The diagram should show the composition of each wire harness, how many branches there are on each harness, how many wires there are on each branch, the color of the wire and what the stripes are. Two, the length of the wire harness The length of the wire harness includes the total length of the wire harness, the length of each branch and the length of the interval between two wire ends. Three, connection code and connection mark The number of electric appliances on the car is large and complex, in order to make the connection correct, each connection point should be marked with connection code and connection mark, so as to facilitate the connection. Four, the adapter Because there are multiple wiring harnesses, wiring harnesses and wiring harnesses, branches and wiring harnesses, or branches and electrical appliances are all connected through the connector, it should be indicated how many wires on each connector, where each wire is located in the wiring hole of the connector, what kind of shape of the connector, whether the adjacent several connectors are easy to be confused. Color of wire In order to make you understand the...

  • The challenge of wiring harness supply reflects global logistics
    Sep 28, 2022 The challenge of wiring harness supply reflects global logistics
    The challenge of wiring harness supply reflects global logistics     Wiring harnesses became an industry hot spot when the war in Ukraine caused a sudden shortage, but the challenges facing the industry go well beyond the events of 2022.   Due to advanced driver assistance features and the already severe lack of automation and high chip requirements in manufacturing, increasing complexity makes automotive wiring harness production one of the most critical development areas in the industry.   Auto Wire harness     Increasing sensor technology and driver assistance features in cars are making them safer and providing drivers with peace of mind.   Autopilot mode is on the rise in popularity, but even relatively basic cameras to help with parking and infotainment displays can make wiring harps more complex and require more high-speed data cables. Electrification adds extra complexity by introducing battery and brake regeneration management, which means more computing power to make the car as efficient as possible. The more wires and structures are needed, the greater the challenge of supplying the parts and actually making the harness.       Automation Automation in harness manufacturing comes from two sources: the need to make production lines and harness manufacturing processes more efficient, and on the vehicle side, the increasing need for sensors and computers to manage advanced driver assistance systems (ADAS).       Although fully autonomous vehicles are still a long way from production, consumers now expect a variety of driver assistants in their cars. Features such as lidar or other camera technology increase the need for a new data line that must be high-speed enough to provide information in real time.   Companies such as Aptiv are providing the technology for smart cars. Do Sohn, Aptiv's global director of innovation, will speak at the Automotive Wiring Harness Conference in Detroit in October. Also, manufacturers need to look for new technologies, such as fully automatic stranding. Simon Abegg, director of twist machines in Komax's product group, will detail the new robotic process, even for 0.13mm wires. Bob Potock, Zuken's vice president of marketing, will also talk about how digital visualization can help set up wiring harnesses and streamline processes.   Connection     The increasing complexity of wiring harness design, the need for faster cables, and the increasing amount of data being transferred in the car mean that the speed at which data can be moved is important. Frederic Holtzman and Johannes Schmid argue that copper wiring is an essential part of this, not a limitation, and he will show how wiring has been able to reach 100G in automotive wiring harnesses, but the problem lies more in semiconductors. Trying to make the most of lightweight wiring will be key to driving vehicle automation.   Electrification     As the auto ...
